Our Verdict
ViewSonic VG1655
MSI Optix MAG274QRF-QD
The MSI Optix MAG274QRF-QD and the ViewSonic VG1655 are two different monitors. The MSI is a standard monitor with a 1440p resolution and 165Hz refresh rate. It has more gaming features than the ViewSonic, like VRR support, a very quick response time, and low input lag. Since it's a regular desktop monitor, it also has a stand with much better ergonomics. The ViewSonic is a portable monitor with a 1080p resolution, but it has much better text clarity with its smaller screen.
